Description
Technical Field
The utility model belongs to the technical field of conveying equipment technique and specifically relates to a spiral network chain and spiral cooling tower are related to.
Background
A spiral mesh belt, or spiral mesh belt, is a conveyor mesh belt, one side of which spirally surrounds the outer side of a cylindrical central cylinder and is conveyed along with the rotation of the central cylinder. Because the outside of one central cylinder can surround the spiral net chain with the length being several times of the circumference of the central cylinder, a longer conveying path can be provided in a limited space; and the conveying time or speed of the spiral net chain can be adjusted and controlled by adjusting the rotating speed of the central cylinder. The above-mentioned characteristics of the spiral net chain make it widely used in cooling, proofing, baking and other processes requiring time control.
Usually, the spiral net chain transports the product from the linear conveying section to the spiral bending section outside the central cylinder body, and finally to the linear conveying section to transport the product out. Because the spiral net chain needs to be switched between the linear conveying section and the bending section, and the winding distance of the side edge of the spiral net chain close to the central cylinder body of the bending section is shorter than that of the other side edge, the spiral net chain is generally formed by mutually parallel and movably connecting a plurality of net chain units capable of moving relative to each other, and therefore the distance between the net chain units can be changed, so that the length of the side edge of the spiral net chain is changed to a certain extent.
In order to realize that the central cylinder drives the spiral net chain to convey, the side edges of the net chain units are provided with teeth, the central cylinder is provided with an upright post, and the upright post is clamped in the two teeth of the adjacent net chain units to realize the conveying of the spiral net chain. However, if a product with a smaller volume needs to be transported, the distance between each net chain unit needs to be reduced (i.e. the pitch is reduced), and when the interval between teeth is too small, the upright column cannot be clamped between the teeth, and the central cylinder cannot drive the spiral net chain to be transported; if the upright post is arranged too thin, the bearing force is weak and the upright post is easy to damage.
In order to solve the above problems, a mesh wire or a mesh structure is arranged between adjacent mesh chain units, that is, the pitch of each mesh chain unit is kept large, and the product is prevented from falling down through dense mesh. However, the mesh or grid structure arranged on the mesh chain unit has the following defects: the net wire or the net structure and the net chain unit have a sanitary dead angle, the cleaning is not convenient and thorough, and the manufacturing cost of the structure is increased.
